Quantitative Models and Construction Methods - Model Name: Style Rotation Model Model Construction Idea: The model is built from micro-level stock factors, focusing on valuation, market capitalization, volatility, and momentum. It integrates a style timing and scoring system to construct a monthly frequency style rotation framework[1][6] Model Construction Process: 1. Start with 80 base micro-level factors selected based on the Dongwu multi-factor system[6] 2. Generate 640 micro-level features from these base factors[6] 3. Replace the absolute proportion division of style factors with commonly used indices as style stock pools to create new style returns as labels[6] 4. Use a rolling training random forest model to avoid overfitting risks, optimize feature selection, and derive style recommendations[6] 5. Construct a framework that transitions from style timing to style scoring and finally to actual investment decisions[6] Model Evaluation: The model effectively avoids overfitting risks and provides a comprehensive framework for style rotation[6] Model Backtesting Results - Style Rotation Model: - Annualized Return: 21.56% - Annualized Volatility: 24.17% - IR: 0.89 - Monthly Win Rate: 58.82% - Maximum Drawdown: 28.33%[7][8] - Excess Performance (Hedged Against Benchmark): - Annualized Return: 13.45% - Annualized Volatility: 11.47% - IR: 1.17 - Monthly Win Rate: 66.18% - Maximum Drawdown: 10.28%[7][8] Quantitative Factors and Construction Methods - Factor Name: Valuation, Market Capitalization, Volatility, Momentum Factor Construction Idea: These are foundational style factors used to construct the style rotation model. They are further refined into micro-level features and integrated into the model's scoring and timing system[1][6] Factor Construction Process: 1. Valuation: Derived from traditional valuation metrics such as P/E, P/B, and dividend yield[6] 2. Market Capitalization: Categorized into large-cap and small-cap stocks based on market size[6] 3. Volatility: Measured using historical price fluctuations[6] 4. Momentum: Calculated based on past price trends and returns[6] Factor Backtesting Results - Factor Performance (2025, Multi-Factor Timing Results): - Valuation: -2.00% - Market Capitalization: 4.00% - Volatility: -6.00% - Momentum: -8.00%[10][17] - Factor Performance (2025, Actual Factor Returns): - Valuation: 2.00% - Market Capitalization: 6.00% - Volatility: -4.00% - Momentum: -8.00%[10][11] Additional Notes - Latest Style Timing Directions (May 2025): Value, Large-Cap, Reversal, Low Volatility[14] - Latest Holding Index (May 2025): CSI Dividend Index[15]
